VERSATILE TRIGGERING
Triggering gives a stable display and lets you zero in on specific parts
of complex waveforms.
What you need
 All oscilloscopes provide edge triggering, and most offer pulse width triggering.
 To acquire anomalies and make best use of the scope’s record length, look
for a scope that offers advanced triggering on more challenging signals.
 The wider the range of trigger options available the more versatile the scope
(and the faster you get to the root cause of a problem!):
- A & B sequence triggering; delay by time or delay by events
- Video triggering on line/frame/HD signals, etc.
- Logic triggering: slew rate, glitch, pulse width, time-out, runt, setup-and-hold
- Communications triggers: embedded system designs use both serial
(I

C, SPI,CAN/LIN, USB …) and parallel buses.

Triggered display
Triggering synchronizes the horizontal sweep at the correct point in the signal, rather than
just starting the next trace at the point where the present trace happens to finish. A single
trigger acquires all input channels simultaneously.
